obviously most of the bike's circuitry wouldn't like 24v; probably fry the
ECU, for one thing. What Sparky and I were discussing was the starter on an
isolated circuit, with the remainder of the bike still running 12v.
Running 2 batts in parallel (or one BIGGER batt)-- as you suggest-- would
give more amp-hours, and the ability to sustain cranking. The way it would
help an over-worked starter is that the starter tends to stall, and draw the
voltage (in the small battery) down below 12v (actually, 12.6); with a lot
more amp-hour capacity it can't draw-down the voltage, and there is more
likelihood that the engine will crank.
24v would make it almost certain that the engine will crank.
Both are useful candidate solutions, with different advantages.
Anybody heard anything about using compression releases on 4-cyl engines w/
electric starters? (John Robinson, maybe?)

Hi Russ, no, the batteries are wired to keep the 12v system, plus to
plus, minus to minus; the rest of the bike can't run on 24v. I'm not a
battery expert, others on the List are, but I think it's something about
the total amperage capacity being increased, the CCAs, or something.
The battery system just has more 'balls' to crank the high-compression
engine better. I remember when we had a Cadillac with the 500 cubic inch
V8 some years ago, my garage pal said, "Bill, if that was my car, I'd
put the biggest battery I could get in there, to crank that baby!" And
he was right, the biggest CCA battery available cranked it and ran it
better than a smaller CCA alternative. Bill
